Thought experiment; You entangle a pair of particles. a chrono-naught takes one half of the pair and gets into Eisenstein's train, which now encircles the earth, and is then accelerated to .999 the speed of light and continues around the Earth for a million years or so. the other half of the entangled pair is placed in a time capsule and sealed for a million years or so. An observer on the moon would see a pair of entangled particles, one racing around the planet, the other sitting in a box. The chrono-naught would have slowed his passage through time, while the particle in the box would have experienced normal time passage. (relative to each other) But what happens when both particles are stopped at a predetermined point in time set by the time capsule box and then a message is passed from the chrono-naught VIA the entangled particle to the other particle in the box? Is the past talking to the future?
